angular range is 300 degrees with a linear change in value. The
resistance value is 10k ohms, perfect for Arduino use. This may also be
known as a rotary angle sensor.

The RTC module is a
member of Twig. It is based on the clock chip DS1307 which supports the
I2C protocol. It uses a Lithium cell battery (CR1225). The
clock/calendar provides seconds, minutes, hours, day, date,month, and
year information. The end of the month date is automatically adjusted
for months with fewer than 31 days, including corrections for leap year.
The clock operates in either the 24-hour or 12-hour format with AM/PM
indicator.

Grove – LED Bar is comprised of a 10 segment LED gauge bar and an MY9221 LED controlling chip. It can be used as a indicator for remaining battery life, voltage, water
level, music volume or other values that require a gradient display.

The LinkIt ONE development board is an open source, high performance
